An oven dry sand mass with a dry unit weight of 105pcf and Gs of 2.70 is placed outdoors in a container. Overnight, it rains. As it rains, the total volume of the soil specimen within the container remains the same, yet the S increases to 55% by the time the rain is over for the night. a. Determine the new total unit weight of the soil after the rain in units of pcf. Express your answer in four significant figures. Show full phase diagram.

A sample of sand has the following properties: Moist mass = 625.2 g Dry mass = 589.9 g absorption = 1.6% Find the surface moisture in %. Use 1 decimal place only for your final answer.
The saturated clay sample was weighed in a container and the total weight was 7.4 N. 24 hours 105 degreesAfter waiting in the oven, the container was weighed again, this time it was measured as 5.6 N. The weight of the container is given as 0.7 N. Given the specific gravity of 2.66 for the soil, a) water content b) void ratio c) porosity d) density and e)Calculate the unit weight.

A dry sand is placed in a containerhaving a volume of 0.0089 cm3. The dry weight of the sample is 0.011 grams. Water is carefully added to the container so as not to be disturbthe condition of the sand. When the container is filled, the combined weight of the of soil plus water is 0.0144 grams. With this, find the moisture content, moist unit weight, dry unit wait, void ratio, the porosity, and degree of saturation. for a saturated soil show that; ????=(?/?)(1+?/1+?)??
